## Interface StatefulMappingFunction<F extends Item,T extends Item>

- All Known Implementing Classes:
    ForExpression.MappingAction, ForItemMappingAction, ForSequenceMappingAction

      public interface StatefulMappingFunction<F extends Item,T extends Item>

  MappingFunction is an interface that must be satisfied by an object passed to a MappingIterator. StatefulMappingFunction is a sub-interface representing a mapping function that maintains state information, and which must therefore be cloned when the mapping iterator is cloned.
